ABSTRACT:
A process for producing an alkoxyacetic acid which comprises contacting carbon monoxide with formaldehyde, an alcohol, water, and a catalyst comprising hydrogen fluoride in a reaction zone and under reaction conditions effective to form an alkoxyacetic acid including a temperature between 0.degree.C and 100.degree.C and a carbon monoxide partial pressure between 10 and 4000 psig. By using an excess of alcohol or omitting water, alkyl alkoxy ester, i.e., alkyl alkoxyacetate, can be produced.
Also, alkyl alkoxyacetate can be produced from dialkoxymethane by reaction of dialkoxymethane with carbon monoxide using hydrogen fluoride as a catalyst.
